I just drove mine home and noticed the pressure on the tires was set at 33 rear and 34 front. I just made them 42PSI all around. Anyone have any problems at that pressure?

The sidewalll reads 51PSI. 16 inch wheels.

Also I have 2 Honda Hybrids in my stable so this will be a good comparison once I put synthetic oil in.
Anyone use anything other than 5W30?
